Popis:	The stochastic vibration control of nonlinear vehicle system under random road excitation is an important research subject. In this paper, based on a more practical and complicated nonlinear vehicle system with torsion-bar-support suspension, the vertical coupling motion between suspension and wheel is considered, and the MR damper is used for the vibration control of the vehicle system under random road excitation. The dynamic differential equations of the two-DOF vehicle system with MR damper are established. Then the HJB equation is established according to the stochastic dynamic programming principle. The feedback control law is designed based on the equation and control boundedness of the MR damper. The control effectiveness is evaluated by comparing the stochastic responses of semi-actively and passively controlled systems. The bounded time-delay control characteristics and the improvement of the bounded time-delay control for the nonlinear stochastic vibration of the two-DOF vehicle system are discussed.
